\ MULTIPLE ROCK-CRUSHER.

Specification of Letters Patent.

Patented Dec. 10, 19O7' l Application led .Tune ll. 1906. Serial No. 321.096.

To all whom it may concern:

Be it known that I, EDWIN S. PHILIPS, a citizen of -the United States, residing at Kennett Square, county of Delaware, and State of Pennsylvania, have invented a new andv useful Improvement in Multiple Rock- Crushers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

The object of my invention is to provide an improved multiple jaw-Crusher for crushing rocks, ore, stones, etc.

The invention consists of a machine having many of the essential characteristics of jaw machines of the type shown in the patent to George W. Taft, No. 458,740, September 1, 1891, but modified and reorganized to adapt it to receive and operate a plurality of jaws.

. The invention also comprises certain other improvements in construction and arrangement hereinafter set forth.

In the drawings: Figure 1 is a plan view, partly in section, of the crusher. Fig. 2 is a longitudinal vertical section. Fig. 3 is a detail view, in side elevation, of the fixed jaw, fixed die and key-bolt. Fig. 4 is an end view showing the fixed aw, side plate, and key-bolt.

The frame of the machine comprises the side plates 10 having foot flanges 11 for bolting to the bed timbers 12. Riveted to the outside of the side plates 10 are the heavy pedestals 13, also having foot fianges 130, and carrying the end journal boxes 14 for ,the main cam-shaft 15.

Extending through the brackets 13 and side plates 10 and between the side plates are bolts 16. Extending between the side plates 10 is the cross-brace 17 having projections 18 forming recesses engaging the bolts 16. The cross-brace is also provided with end flanges 172 bolted to the side plates. The brackets 19, carrying the two journal boxes 20 for supporting the main cam shaft between adjacent double cams 21, is secured to the cross-brace 17 by means of bolts 171 extending through the brackets and caps 170 on the cross-brace. The three double cams 21 are each elliptical in shape and are secured to or integral with the main cam shaft 15 and are so arranged thereon that their diameters extend at angles of degrees with reference to each other.

The tumbler levers 22 are each pendulous from a shaft`23 which extends between the side plates 10 and is secured thereto from the outside. The tumbler levers are hollowed out at their'lower ends to form side flanges 24 and a front shell 26. Between the side fianges' 24 of each tumbler-lever is the tumbler-roller 25, whose axle revolves in bearings in the side fianges. The front shells 26 of the tumbler rollers form guards to keep the rock fragments from the rollers and cams.

` The moving jaws 27 are pendulous from a shaft 28 extending between the side plates 10 and secured thereto from the outside. The opposing faces of the moving jaws 27 and tumbler levers 22 are provided with dovetail recesses, within which `are fitted the toggle seats 29. The toggles 30 are seated at their opposite ends in the toggle seats 29. The toggles 30 are removable so that larger or smaller toggles may be substituted to vary the size of the crushed product.

Depending from the plate 17 are lugs 31. Rods 32 are pivoted to the lower ends of the moving jaws and extend rearwardly through the lugs 31, which form seats for the springs 33 surrounding the rods 32 and working against collars 320 secured to the rods. The springs 33 assist in drawing the moving jaws backwardly and in holding the toggles 30 in their seats.

The removable and reversible face-hardened dies 34 are set into recesses in the faces of the moving jaws 27. To hold the dies in place, wedge-shaped key blocks 35 are provided between the tops of the dies and the upper faces of the die recesses. Bolts 36 extend through the key blocks 35 and the jaw body. By tightening the bolts, the dies 34 are forced downwardly against their dovetail seats.

The fixed jaw 38 is secured between the side plates 10 by means of bolts 39. The fixed jaw is rovided with a recess to receive the remova le and reversible die 40. The jaw and die are provided at each end with alining key-ways, the key-ways in the die having tapered lower walls. Through each pair of aiming key-ways in the jaw and die extends the wedge-shaped key bolt 41, which is of substantially less width, at its wide end, than the die orifice. By tightening this keybolt, its tapered side bears against the tapered wall of the die-orifice and its opposite straight side bears against the upper straight wall of the jaw orifice, thus forcing the die against its dovetail seat.

The side plates l0, from a point in front of the moving jaws, are concaved downwardly to a level with the fixed aw, thereby permitting the more free introduction of the material to be crushed. To protect the top of the fixed jaw, a cover plate 42 is secured to the top thereof. To protect the upper ends of the movable jaws, an upright face plate 43 extends from the upper ends of the dies 34 to the top of the side plates and is there bolted to flanges on plates 44 bolted respectively to the side plates. To protect the side plates from wear due to the crushing of stone, rectangular check plates or liners 45, reversible and interchangeable side for side, are secured to the inner face of the side plates opposite the crushing faces of the dies 34. Small wearing plates 46 are also bolted to the inner faces of the side plates opposite the toggles 30.

47 are fly wheels secured to the main-cam shaft. These fly wheels serve as belt wheels for driving the machine, and also as traveling wheels -in transporting the machine from place to place when the supporting timbers are removed. 4S are additional bolts extending between the side plates for holding them securely in osition.

While I have escribed a machine comprising three moving jaws, it will be understood that any number of jaws greater than one may be employed. If two jaws are employed, but two operating cams are provided whose longer diameters are arranged at an angle of 90 degrees with reference to each other. In a four jaw machine, the four operating cams are preferably arranged so that their longer diameters are at angles 45 degrees apart, or less preferably alternate cams may be arranged so that their longer diameters extend arallel to each other and at an angle of 90 egrees with reference to the remaining cams.

/Vhen the main cam-shaft is rotated, the three double cams act successively to move forwardly the tumbler-rolls and tumbler levers, which in turn, through the toggles move the movable jaws toward the fixed. j aw, crushing the material held therebetween. With the double cams arranged as. described, each movable jaw will operate twice. during one rotation of the main cam-shaft and the three movable jaws will operate successively,

movable jaw of the combined width of the three movable jaws, but with much less strain upon the supporting parts at any one time, thus reducing the power required to operate the machine.

Having now fully described my invention, what I claim and desire to protect by Letters Patent is:

1. In a rock crusher, the combination with the side plates, of a shaft between the side plates and a plurality of moving jaws swinging thereon, a second shaft between the side plates back of and below the first shaft, and a plurality of tumbler-levers, corresponding in number to the moving jaws, swinging thereon and actuating the moving jaws respectively, a main cam shaft between'the side plates back of and below the second shaft, cams fixed thereon corresponding in number to the moving jaws and actuating the tumbler -levers respectively, a crossbrace between the side plates back of the main shaft, and brackets on the cross-brace having bearings for the main shaft extending between adjacent cams, substantially as described.

2. In a rock crusher, the combination with the moving jaw and actuating mechanism therefor, of a fixed jaw having a key-bolt orifice extending from front to back, a die applied to the face of the fixed jaw, and extending above the orifice in the xed jaw and having, between its upper and lower ends, an orifice, in line with the jaw orifice, having one tapered wall, and a key-bolt having a tapered side bearing against the tapered wall of the die orifice, the opposite side of the keybolt bearing against the corresponding wall of the jaw orifice, substantially as described.

3. Infa rock crusher, the combination with the side plates, of the fixed and moving jaws between the side plates, dies carried by the jaws respectively, and actuating mechanism for the moving jaw, a shaft, from which the moving jaw is hung, above the level of the fixed jaw, and between the side-plates, the upper edges of the side plates being cut away from above said shaft to substantially the level of the top of the fixed jaw, an upright face plate extending between the side plates in front of that part of the moving aw above its die, and a cover plate overlying the fixed *l j aw and die, substantially as described.

In testimony of which invention I have hereunto set my hand, at Philadelphia, on this 5th day of June, 1906.

EDWIN S. PHILIPS.
